a similar groove ; on each side of the latter the tip is slightly- 

 swollen. On the dorsal side the ninth segment has a row of 

 hooklets at the tip, parallel to a similar row on the tip of the 

 abdomen, both rows interrupted in the middle. Length 11 mm. 

 The shell is split across the occiput and along the antennae 

 exteriorly, the prothorax and mesothorax are split in the median 

 line, the suture between the prothorax and mesothorax is some- 

 what broken, and the mesothorax is split from the metathorax. 

 The metathorax and first segment of the abdomen are firmly 

 united. In counting the segments of the abdomen I have 

 followed the numbering which is usually employed. 



Imago^ $ . Pale ashy-white, fringes paler than wings, an- 

 terior wings a little darker towards base and costa ; back of 

 abdomen dull orange yellow, with a row of black spots in the 

 median line (a slate colored line supplying the place of the spot 

 on the first segment), and two similar rows each side. Body 

 beneath of the same color as wings. Antennae and clypeus 

 dark slate color, palpi black at tip. Legs black, the tarsi ashy 

 beneath, the anterior coxae mostly orange, as are also the 

 thorax just under the wings, the base of the costa of the wings 

 beneath, and the palpi excepting the tips. Length of fore wing 

 14 mm., of body 11 mm. ; greatest breadth of fore wing 7 mm. ; 

 expanse 32 mm. 



Mr. Lintner's specimen from Center, N. Y. (Ent. Contr., 

 iii, p. 146), differs from mine in being a $ , and exj)anding 

 1.62 in. [=41 mm.]. Mine agrees with Fitch's except in 

 being slightly suffused with ashy, and in the tarsi being black 

 above and ashy beneath. But Fitch does not mention the con- 

 spicuous color of the abdomen, and as his specimen came from 

 Mississippi, it may not be identical with the northern species. 

 I add, therefore, his description for comparison. 



'•'•Hyphantria coUaris [Fitch, 3dRept. p. 65, § 89]. A moth 

 closely related to the preceding \^H. textor'\ and doubtless pos- 

 sessing the same habits has been sent me from Mississippi and 

 probably occurs throughout the Southern States. It is milk 

 white and glossy, its head, neck, base of the outer edge of the 

 fore wings and the anterior hips are pale ochre yellow, and its 

 feet pale brown. Width 1.35 [= 34 mm.]."
